Engineering, Image Processing

This dataset entails MATLAB code that implements the following topics: (1) Bioreactor calibration by means of a calibration target, (2) Image preprocessing, (3) Lagrangian LED Particle recognition, (4) Image distortion removal and translation into real space and (5) Particle track recognition. The code was written by Maximilian Kamp in the context of his Bachelor thesis.
